Description

We report for the first time the formation of a metal amidehydride solid solution. The dissolution of KH into KNH2 leads to an anionic substitution, which decreases the interaction among NH2-ions. The rotational properties of the high-temperature polymorphs of KNH2 are thereby retained down to room temperature.
